What is Radon, and why would I need a survey?

Radon is a colourless, odourless, radioactive gas. It is present in most homes and businesses. If you are selling a house in a radon affected area, your buyers will now ask for a Radon survey.  If you are an employer, your risk assessments should include Radon.

Who needs a Radiation Protection Advisor?

A Radiation Protection Advisor (RPA) must be consulted if employers conduct activities that involve working with Ionising Radiation. Schedule four of the Ionising Radiations Regulations provides further details of when an RPA needs to be consulted.

What training do you provide?

We offer Radiation Protection Supervisor (RPS) training, and general Radiation Awareness training. This helps to ensure that employers are compliant with regulations.  Options are available for sectors such as Radon, veterinary practices, schools & colleges.

Radon - Dr Paul - Jarvis Nuclear

What Is Radon and Where Does It Come From?

Radon is a colourless, odourless, radioactive gas, and is naturally created during the radioactive decay of Uranium, present in soil and rocks.  You cannot taste it – however, it can sometimes be detected in water.  Radon is present in varying concentrations in homes and workplaces, and according to the World Health Organisation, is the second largest cause of lung cancer.

Every building contains Radon at some level, however, higher concentrations are often prevalent when windows are closed and heating is on.  If an area has >1% probability of a property exceeding the Action Level, it is deemed a Radon Affected Area.  Radon concentration is measured in terms of becquerels per metre cubed. The becquerel is a unit of radioactivity and is equivalent to the number of decays per second.
